Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

FDMS7558S N-Channel PowerTrench SyncFET October 2014 FDMS7558S TM N-Channel PowerTrench SyncFET 25 V, 49 A, 1.25 m Features General Description The FDMS7558S has been designed to minimize losses in Max r = 1.25 m at V = 10 V, I = 32 A DS(on) GS D power conversion application. Advancements in both silicon and Max r = 1.75 m at V = 4.5 V, I = 28 A DS(on) GS D package technologies have been combined to offer the lowest r while maintaining excellent switching performance. This DS(on) Advanced Package and Silicon combination for low r DS(on) device has the added benefit of an efficient monolithic Schottky and high efficiency body diode.
